The good news about this and the whole River Song thing is that it stops two rumors that were doing the rounds about this series.
One is that Mat wont be Doctor 11, but a young Doctor 1, and two there will be a massive re-set button in the last RTD/Tennant special which will lead to a re-boot.

But - I always thought she knew the Tennant Doctor, which doesn't fit so well unless she appears right at the end of this series...which I doubt.

On a related note, what is happening to the Sarah Jane production team now that Davies has gone? And would he still be "doing" Torchwood assuming it's coming back, which it is?

RTD is still involved with this series 3 of SJA, and has said before he would like to do more Torchwood. As opposed to Doctor Who, both shows were created by him (although obviously SJA has an existing non RTD created character), and both are very much his shows.
